JOSEPH E. 'FORSYTH,. OF CHICAGO, ILLINOIS.-

To all whom it may concern:

Be it known that I, JosEPn E. Fonsrrn. a citizen of the United States. residing at Chicago, in the county of Cook and State of Spepification of Letters Patent. Application filef- July 18.1906. Serial No. 326.656;

brace the lug abetween them. The bifurcations have bolt-holes. which receive bolts 6 passing through the elongated openings (1.

' The bifurcations are suflicientlv yielding to Illinois. have invented a new and useful Improvement in Train-Pipe COU])l1IlgS,'0f wh ch a the following is a specification.

\I v invention relates particularly to means for supporting the coupling-heads of automatic train-pipe couplings.

My primary object is to provide improved means forholding and centering couplingheads in a reliable manner; while permitting all necessary freedom of movement thereto to compensate for relative movement of the cars under any working conditions which mav be encountered.

The invention is illustrated in'its preferred embodiment in the accompanying drawings, in wlnch.

Figure 1 represents a enable the hanger after adjustment on the lug a to be firmly clamped in place.

, The coupling-head C is provided with the usual guide-prongs c, a passa e 0 iii connection with the signal-pipe of the train, a passage c for connection with the brake-pipe of the'train, and a passage 0 for connection with the steam-pipe of the train. Projecting rearwardly from the central portion of the head is a pi e c, which connects with the passage 0 0 the coupling-head. and which exten s loosely through an opening c in the s ring-plate b L'pon the pipe c in the rear of the hanger B is a collar 0", equipped with prongs 0 which engage the rear face cf the 1 ring b of the hanger.- The pipe e is probroken side 'eleval tional view of a draw-bar of a car with a train-pipe coupling-head supported thereon b v means of my vided with a spline c", which fits in a longitudinal groove c", with which the sleeve c" is provided internally, the rear end of said groove being closed, as indicated at c". The

improved coupling-head f support: Fig. '2, a section taken as indicated at line 2 of Fig. 1: Fig. 3, a section taken as 1 indicated at line 3 of Fig. 1; Fig. 4, a section taken as indicated at line I of Fig. 1, the spring for projecting the coupling-head being i removed Fig. of the hanger shown in Fig. 4 with the spring-plate removed from its socket, and

Fig. 6 a broken sectional view taken as indi- 1 a with the brake-pipe of the train. In the construction shown. A represents cated at line 6 of Fig. 3.

a front or outer face view the draw-bar of a car. B a hanger depending therefrom. and C a train-pipe coupling-head supported on the hanger through the medium of a conical coil-spring C. which serves to" hold it vieldingl v projected and centered.

The draw-bar or car-coupling member A provided with a depending boss (l.supplied with horiz: i'itallv-alined slotted openings (1 and with verticallv-serratetl side'surfaces (1' The hanger B comprises a shank b and a ring The ring has an opening 11*.

' over which fits the large rear end of the coi ical spring C. has hiiurcations which have vertical serrations on their ad acent surfaces and em- The upper end of the shank?) connection is such that when the pipe c moves rearwardlv, as when two couplingheads are brought together in the operation of coupling the cars, the sleeve 1 and the arms carried thereby, constituting a spider; will move rea-rwardlv with the pipe. T liI't aded onto the rear end of the pi ie c is an elbow c, with which is connected a llexihle armored hose c", which in practice coiint cted The tlhow 1: usually occupies a horizontal plane. It is shown rotated to the vertical plane, however. for convenience of illustration. Its front end bears against the sleeve c, affording a stop, when the coupling-head in the advanced position. 'I he ring 71 of the hanger B is provided on its rear surface with a lug c, which tapers rearwardlv to a point c. and fits loosel between two'of the arms c of the spider. This lug serves as a guide for the spider and through the medium of the spider maintains he coupling-head in proper position for cd upling.

It will now be understood that when two cars are brdught together in the operation of coupling the cars the coupling-heads of the train- )ipes will engage each other and will be forced inwardly or retracted. In this action tlie'spiders will be moved away from the rings 1). somewhat, and the pipes 0 will be free to swing in any direction to accommodate the coupling-heads of the train-pipes to anv relative movement of the cars which may occur under the conditions. of use of the cars upon a railway track.

Xo novelty the train-pipe couplinghead herein shown is claimed, the couplinghead being substantially like that shown in my Patent 'Xo. 740,749,, granted October 6.
